Homework Help: Physics

Posted by Traci on Tuesday, September 20, 2011 at 8:39pm.

Two identical point charges are fixed to diagonally opposite corners of a square that is 1.5 m on a side. Each charge is +2.0 ÁC. How much work is done by the electric force as one of the charges moves to an empty corner?

I have W(fe)= -EPE=-q[V(f)-V(i)]. I can't figure out what to do next or if im doing it right to begin with?
